7fe5f10ed0 [POWERPC] PPC440EP Interrupt Triggering and Level Settings
Corrected IRQ triggering and level settings according to latest revision
of the 440EP User Manual (rev 1.24 nov 16, 2007).

The incorrect settings might cause a failure of the network if both
onchip ethernet ports are under heavy load.

7cc955c8fd [POWERPC] virtex bug fix: Use canonical value for AC97 interrupt xparams
The ml300 and ml403 xparameters.h files use different macros for the
AC97 interrupt pin assignments.  This normalizes them to a canonical
value similar to what EDK generates for most other devices.  This is
needed to get ml300 support to compile in arch/ppc.

e701d269aa [POWERPC] 4xx: Fix 4xx flush_tlb_page()
On 4xx CPUs, the current implementation of flush_tlb_page() uses
a low level _tlbie() assembly function that only works for the
current PID. Thus, invalidations caused by, for example, a COW
fault triggered by get_user_pages() from a different context will
not work properly, causing among other things, gdb breakpoints
to fail.

This patch adds a "pid" argument to _tlbie() on 4xx processors,
and uses it to flush entries in the right context. FSL BookE
also gets the argument but it seems they don't need it (their
tlbivax form ignores the PID when invalidating according to the
document I have).

Unfortunately not by trying to compile this driver for his hardware but

0fbbeba242 [POWERPC] Ocotea board: ntpd complains that the frequency error exceeds the tolerance
Lifted from http://bugzilla.kernel.org/show_bug.cgi?id=8182

Steps to reproduce:
- Boot an Ocotea board with the mainline 2.6.20.1 kernel.
- Create an /etc/ntp.conf file with at least one NTP server and iburst mode set.
- Issue the command "ntpd -g".
- Wait about two minutes.
- Verify ntpd's status via "ntpq -pn" and by looking in /var/log/ntp.

This fixes this problem by adjusting the expected clock frequency.
